Innergie claims their new mCube Mini is the world's smallest travel charger for laptops. A very good thing, especially if you travel light. I refuse to pack more than one duffel bag no matter how long I'm away.

Specifically designed for cars and airplanes, the mCube Mini can be powered by either a 12V or a 15V outlet and can support netbooks and laptops that need up to 65W of power at 15-21V. It also has a USB port so you can charge other portable gadgets at the same time. Again, it's small—60 x 26 x 18mm to be exact, so it's fairly comparable in size to a typical cellphone. Available now for $70. [Innergie via Slashgear]
